With my ftp client i have it set as all newer dates at the top of the list. That way i can see at a glance quickly which are the newer files added.
Just checked ftp to day and there is a lot of folders with ghost dates, where something has been uploaded and then removed. The folder date hasn't changed back to the last file upload date for the folder.
Magix have you a setting to make this possible, so no future ghost dates appear.
